Development of hydraulic expansion technology for large stainless steel elbow

The basic technological process of stainless steel elbow is that: under the material roll bending welded into a closed ring shell ring shell internal pressure forming segment. Usually the processing technology is to use the mold to suppress the multi block housing, and then welded to complete. Many processes require different fixture or tooling, high manufacturing cost and cycle length, and the process of large thin wall parts is very poor. The development of hydraulic expansion technology for large thin-walled parts of the forming process.Stainless steel elbow is a kind of thin-walled parts, for the processing of thin-walled parts, the process is difficult. The development of hydraulic expansion technology provides a new way for the forming of large thin wall parts. The model free hydraulic bulging technology is a new type of hydraulic forming technology, which has the characteristics of low cost, short processing cycle, good forming and so on. The basic process is: the plate or after bending single curvature shell plate, welded closed polyhedron.Stainless steel elbowThen, under the action of internal pressure, the shell has a plastic deformation, and gradually tends to be ideal. The basic process of the large stainless steel elbow is: under the material, roll bending, welding into a closed ring shell, internal pressure forming.Usually the processing technology is to use the mold to suppress the multi block housing, and then welded to complete. Many processes require different fixture or tooling, high manufacturing cost and cycle length, and the process of large thin wall parts is very poor. The development of hydraulic expansion technology provides a new way for the forming of large thin wall parts.Zhejiang Yaang Pipe Industry Co., Limited (www.yaang.com) provides stainless steel tee, stainless steel flange, stainless steel head, so different diameter pipe etc., affordable, welcome the masses of old and new customers to come to consult Oh!Source: Zhejiang Yaang Pipe Industry Co., Limited (www.yaang.com)
